The Ladle Slide Gate Plate is a crucial component in the steelmaking and continuous casting process, used to control the flow of molten steel from the ladle or tundish to the crystallizer. It ensures stable and controllable steel flow, enhancing the quality of the cast steel while reducing operational risks. Xintai Refractory manufactures these slide gate plates using high-quality refractory materials, providing excellent thermal shock resistance, corrosion resistance, oxidation resistance, and mechanical strength.
Designed for converters and ladles, the slide gate plate allows precise flow regulation, emergency shutdown, and operational flexibility, making it an essential part of modern steel plants.
